Connecting Second Load Center To Meter Base

I'm working on a project to get power to a carport and set of storage sheds that are part of a 4-plex of condominiums. The only practical way to get power from the main building is to install a load center next to the 4-pack meter base. Each section of the base has a 125 Amp main breaker and the panel has a side knockout. I am planning to locate a small (125 Amp) outdoor load center next to the meter base and splice into the feeder of one of the condo units using a pre-insulated splice block (like a Polaris IPL series). The meter base is quite large and there is plenty of room for a splice. I have gotten conflicting advice on whether or not doing a splice in a meter panel is a code violation. One individual suggested using a lug doubler on the main breaker, but this appears to be a hard item to find.

I don't know where you're located but to the best of my knowledge, there are no states that allow unlicensed people to work on multi-unit dwellings. I would suggest that for your own safety and liability, you get a licensed electrician to do this.

No, the splice I am talking about would be down stream (so to speak) of the 125 amp breaker for one of the condo units, so simply turning off that breaker would give me (or my electrician) a dead circuit to work on.

A house panel is not an option as it would require adding a new meter. The local impact fees for a new meter installation exceed $1500. The power is for a security light that would be on a motion sensor. The cost of the power would be less than $10 per year. The plan is to have the owner of the condo supplying the power be compensated out of association fees.

Codes aside, high amperage connections need to be torqued to a certain tightness or they will heat up.

Main panels will say how tight to torque the main lugs.

So very important that any connectors used are rated for the amperage and very important to follow directions about torque tightness. And if using aluminum wiring, research using anti-oxidant "goop" with these connectors which would typically be done with a panel lug. I don't know if these connectors come with a "magic" goop or not?

And be sure they are rated for aluminum wiring if that is what you are using.

If they need a hex tool to tighten the screws, you can get these at an auto parts store along with a torque wrench.

Then the instructions may say inch pounds instead of the foot pounds on the torque wrench. There are 12 inch pounds to 1 foot pound. Google.com even can convert this...
